Is 16GB RAM enough? We put Ubuntu 26.04 to the test on Lenovo's latest 16-inch business powerhouse
The corporate laptop landscape has been in flux since Microsoft's aggressive push toward Windows 11, leaving many professionals questioning their operating system choices. With memory prices hovering around €200 for a 16GB upgrade and the growing bloatware concerns on Microsoft's platform, Linux has emerged as an increasingly attractive alternative for discerning users.
Lenovo's ThinkPad series has long been a favorite among the Linux community, offering out-of-the-box compatibility that rivals even dedicated Linux hardware vendors. The new ThinkPad T16 Gen 5 continues this tradition, but how does it actually perform when you ditch Windows entirely? We decided to find out.
Why Choose Linux on Your ThinkPad?
Before diving into our test results, it's worth understanding why more professionals are making the switch. Windows 11 system requirements have left many older machines behind, while the operating system itself has become increasingly resource-heavy. The constant telemetry, pre-installed applications, and background processes consume significant system resources that could otherwise be used for actual work.
Linux, by contrast, offers a leaner experience. Ubuntu, one of the most user-friendly distributions, requires substantially less RAM to function smoothly, leaving more headroom for your applications. This is particularly relevant given that the ThinkPad T16 Gen 5 comes equipped with 16GB of memory—plenty for Linux users, but potentially borderline for Windows power users running multiple applications simultaneously.
Official Linux Support: What Lenovo Promises
Lenovo has been progressively improving its Linux support strategy, and the documentation for the ThinkPad T16 Gen 5 explicitly lists Fedora Linux, Ubuntu Linux, and generic Linux as supported operating systems. This official recognition is crucial for business users who require stability and reliable support from their hardware vendor.
However, Lenovo does offer some caveats—features like the WWAN module might not function perfectly under Linux. While most core components work flawlessly, niche hardware like cellular modems can sometimes present compatibility challenges depending on your specific configuration.
Setting Up Ubuntu 26.04: Our Testing Process
For our comprehensive test, we used the latest version of Ubuntu (26.04) to evaluate the ThinkPad T16 Gen 5's Linux compatibility. The installation process was straightforward:
- We created a bootable USB drive with Ubuntu 26.04
- IMPORTANT: We disabled Secure Boot in the BIOS to ensure smooth booting from the USB drive
- The installation proceeded without any hiccups
The entire process took less than 20 minutes—remarkably faster than the typical Windows installation experience, which often requires multiple reboots and lengthy setup procedures.
Hardware Compatibility: Everything That Worked Out of the Box
Our test results were overwhelmingly positive. Ubuntu detected and configured every major component correctly, with no manual driver installations required. Here's what worked flawlessly:
- Special Function Keys: Screen brightness controls, volume adjustment, print screen functionality, and the two-stage keyboard illumination—all operational without additional configuration
- Cursor Controls: Both the clickpad and the iconic ThinkPad TrackPoint worked perfectly, with accurate cursor movement and gesture recognition
- Networking: Wireless network connectivity was established immediately during setup, and the Bluetooth module paired with devices without any issues
- Power Management: The familiar power modes available in Windows are also present in Linux, allowing you to balance performance and battery life as needed
A Note About Fan Behavior
We did observe one minor characteristic during testing—the short fan bursts we previously noted in our full review were also present when running Linux. On mains power, the fan occasionally ramps up briefly before returning to silence. This appears to be related to power management policies and wasn't disruptive during normal use.
The Memory Question: Is 16GB Enough?
This is perhaps the most pressing question for potential buyers. With memory modules currently priced around €200 for a 16GB upgrade, the financial decision is significant.
Under Linux, 16GB of RAM provides considerably more breathing room than under Windows. Our testing with multiple browser tabs, document editing, development tools, and media playback showed memory usage hovering comfortably below 8GB during typical business workflows. Power users running virtual machines or working with large datasets might still benefit from more memory, but for the majority of professionals, 16GB proves ample.
The reduced memory overhead of Linux means you're essentially getting more value from the same hardware configuration—something to consider when weighing the purchase decision.
Where to Buy the ThinkPad T16 Gen 5
If you're convinced that the ThinkPad T16 Gen 5 is the right Linux laptop for you, we have great news. The device is currently available at a competitive price of €1,414 from OK2, a trusted Lenovo partner. You can check out the full specifications and place your order at their dedicated product page:

This configuration offers an excellent balance of performance and value, especially when you consider that you're not paying the "Windows tax" and can install your preferred Linux distribution at no additional cost.
Verdict: A Linux Laptop Worth Recommending
Our testing confirms that the ThinkPad T16 Gen 5 is an outstanding choice for Linux users. The hardware compatibility is exceptional, the performance is solid, and the 16-inch display offers ample screen real estate for productivity tasks.
While the fan behavior on mains power is worth noting, it's a minor quibble in an otherwise excellent package. The official support from Lenovo, combined with the mature Linux ecosystem, makes this laptop a compelling option for businesses and individual users alike who want to escape the Windows ecosystem.

Final Thoughts
The ThinkPad T16 Gen 5 represents everything that's good about the ThinkPad legacy—robust build quality, excellent keyboard, and reliable performance. The fact that it runs Linux so well only adds to its appeal.
In a market where operating systems are increasingly trying to lock users into specific ecosystems, the ability to choose your software environment remains valuable. The ThinkPad T16 Gen 5 respects that freedom while delivering the hardware quality that business users expect.
Whether you're a developer, a system administrator, or simply someone who prefers the Linux workflow, this laptop deserves serious consideration. The 16GB memory configuration, while modest by some standards, proves more than adequate for Linux workflows, and the current pricing makes it an attractive proposition for professionals seeking a reliable, Windows-free computing experience.
